I maintain this and other Home Assistant add-ons in my free time: keeping up with upstream changes, HA changes, and testing on real hardware takes a lot of time (and some money). I use around 5-10 of my >110 addons so regularly I install test machines (and purchase some test services such as vpn) that I don't use myself to troubleshoot and improve the addons

If this add-on saves you time or makes your setup easier, I would be very grateful for your support!

Custom Scripts and Environment Variables

This addon supports custom scripts and environment variables through the addon_config mapping:

Meilisearch full-text search: The addon ships with an embedded Meilisearch service that Monica uses by default. The search API listens on http://127.0.0.1:7700 inside the container. Override MEILISEARCH_URL via env_vars if you prefer an external Meilisearch instance—the init script will detect that and skip starting the bundled daemon. You can further tweak Meilisearch by defining extra environment variables through the env_vars option if needed. To secure (or disable) Meilisearch authentication without custom env vars, set the meilisearch_key add-on option; the init script will pass it to both Monica and the bundled Meilisearch instance. If you prefer to manage the key yourself, you can also provide MEILI_MASTER_KEY through env_vars, which the add-on now uses as a fallback when no meilisearch_key is configured. When neither is set (or they are too short), the add-on now generates a persistent 32-byte key in /data/meilisearch_master_key so Meilisearch always starts with a valid master key.
Custom scripts: See Running Custom Scripts in Addons
env_vars option: Use the add-on env_vars option to pass extra environment variables (uppercase or lowercase names). See https://github.com/alexbelgium/hassio-addons/wiki/Add-Environment-variables-to-your-Addon-2 for details.
